From 2dbcb8f0a3250395c0ea8436ac519b6908dc0ee7 Mon Sep 17 00:00:00 2001 From: oliviermartin Date: Thu, 22 Sep 2011 23:05:20 +0000 Subject: ArmPlatformPkg: Changed memory model for the stacks In the previous version, every cores had the same stack size. To avoid to waste memory with secondary core stacks, the primary core stack size is now different from the secondary cores stack size. These are the Stack PCDs and their default values: gArmPlatformTokenSpaceGuid.PcdCPUCoresSecStackBase|0 gArmPlatformTokenSpaceGuid.PcdCPUCoreSecPrimaryStackSize|0x10000 gArmPlatformTokenSpaceGuid.PcdCPUCoreSecSecondaryStackSize|0x1000 gArmPlatformTokenSpaceGuid.PcdCPUCoresSecMonStackBase|0 gArmPlatformTokenSpaceGuid.PcdCPUCoreSecMonStackSize|0x1000 gArmPlatformTokenSpaceGuid.PcdCPUCoresStackBase|0 gArmPlatformTokenSpaceGuid.PcdCPUCorePrimaryStackSize|0x10000 gArmPlatformTokenSpaceGuid.PcdCPUCoreSecondaryStackSize|0x1000 git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12415 6f19259b-4bc3-4df7-8a09-765794883524 --- ArmPlatformPkg/ArmPlatformPkg.dec | 14 ++++++++------ 1 file changed, 8 insertions(+), 6 deletions(-) (limited to 'ArmPlatformPkg/ArmPlatformPkg.dec') diff --git a/ArmPlatformPkg/ArmPlatformPkg.dec b/ArmPlatformPkg/ArmPlatformPkg.dec index 65b4977fdb..c5e40105e6 100644 --- a/ArmPlatformPkg/ArmPlatformPkg.dec +++ b/ArmPlatformPkg/ArmPlatformPkg.dec @@ -49,19 +49,21 @@ # These PCDs should be FeaturePcds.
